8 With respect to this latter point, this can be dealt with comparatively briefly in light of the tree dispute principle published by the Court in Barker v Kyriakides [2007] NSWLEC 292 which is that (even if damage were demonstrated as discussed as a preliminary point by Preston CJ in Robson v Leischke (2008) 159 LGERA 280; [2008] NSWLEC 152) it is the responsibility of persons living in urban environments having the environmental and aesthetic benefits of trees to undertake ordinary reasonable maintenance of their property to remove twigs, leaves, nuts and berries and the like from their property including from their gutters. There is nothing in these circumstances, even if we were satisfied that there was actual damage as a threshold or likelihood of damage to Mr Gallagher's gutters, that we would cause us to displace the tree dispute principle in Barker v Kyriakides. We therefore will not make any order based on his concerns about leaves in his gutters.
